Let's divide 431242 by 42
We want to divide 431242 by 42.

Advancing to step 1:
If we divide 4 by 42, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 42

Let's proceed to step 2:
43 divided by 42 is 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 42 from 43 leaves us with 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 42

Step 3:
If we divide 11 by 42, we get 0 and a remainder of 11.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we subtract 0 from 11, we get 11.
Append the next digit (2) from the dividend to 11 and continue with: 112 / 42

Going ahead to step 4:
The number 42 fits into 112 2 times, leaving a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 102.0
Subtracting 84 from 112 leaves us with 28.
Take the next digit (4) from the dividend and append it to 28, then repeat: 284 / 42

Going ahead to step 5:
The number 42 fits into 284 6 times, leaving a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 1026.0
Subtracting 252 from 284 leaves us with 32.
Append the next digit (2) from the dividend to 32 and continue with: 322 / 42

Step 6:
When dividing 322 by 42, we get 7 with a remainder of 28.
Put 7 as the next digit of the answer. 
Result so far: 10267.0
Subtract 294 from 322 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 7:
280 divided by 42 is 6 with a remainder of 28.
The number 6 becomes the next digit in our result. 
Result so far: 10267.6
Subtracting 252 from 280 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 8:
The number 42 fits into 280 6 times, leaving a remainder of 28.
Record the quotient 6 as the next digit in the result. 
Result so far: 10267.66
Subtracting 252 from 280 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

After the division, we end up with 10267.66 and a remainder of 0.028.
